even the 305s had good torque.

in short races they had enough advantage to be able to take the lt1s...least mine did. but by 1/4 they were quickly running out of steam.

Re: How much HP and TQ from a L98

My buddy let me drive his fully loaded 88 GTA that he has with a L98 and t-tops (I guess that was a dealer option only) and that thing MOVES! It would hang with my LT1, it would not win but for a stock car it was FUN Only problem is that it needs some work and has a lot of polly mounts and the car about shook itself to death at 100mph LOL

I know of a few L98 cars with gears, 6-speeds, and full bolt-ons that run a 13.9 and there is a lot of room for weight reduction in third gens. Just pull off the stock hood and you will see what I mean LOL.

Re: How much HP and TQ from a L98

I have an '89 GTA with the L-98 and t-tops. I believe if I'm not mistaken '89 was the last year you could order the t-tops with the 350 engine combo.

I agree with the above comments about the wicked torque these engines have.

Re: How much HP and TQ from a L98

I hate my TBI 305. luckaly i just bought a 350 with some Vortec heads and roller everything for 500bux. i was stoked about that deal. the heads are brand new too still in the bag! cant wait to go cruise in this thing. its a 92 so its the other bird body style witch not too many people like. but i like it alot so woo woo.
